Just read the following argument that Libraries are doing something illegal by sharing books:
What if book publishers started to sue libraries? at Torrentfreak
"..Yes, libraries! Libraries are evil, evil places. One single copy of a book, movie or music album is borrowed and abused by tens, if not hundreds of self-centred, ignorant pirates. Hell, they even have copiers in most libraries allowing pirates to copy every book on the shelves.."
The argument is flawed in comparing online services like Google with Physical Libraries. In the digital world a "copy" is transmitted from the server to the end user's client (Browser). However in Libraries, no "copies" are made. They are rather circulated. When no copies are made, Howcome copyrights are violated?
